How to Make a Radar (Spider) Chart Online

To make a radar chart, open the Radar Chart Maker and paste a table: one row per measure (the spokes) and one column per person, product or team, with their names in the first row. The chart draws each series as a shape around the centre. Set the Scale maximum — automatic, or 5 for ratings out of 5, 100 for percentages — choose a Grid, and download a PNG, JPG or SVG.

Make a radar chart step by step

1. Open the Radar Chart Maker.
2. Paste or type the table:

Skill,Alex,Sam
Communication,8,6
Technical,6,9
Leadership,7,5
Creativity,9,6
Teamwork,8,8
Planning,5,7

Copy straight from Excel or Google Sheets. 3. Under Options:

• Scale maximum — Automatic, or Set it myself (for example 10 for scores out of 10).
• Grid — Polygon (web) or Circles, and the number of Rings.
• Fill opacity (%), Show points and Show values.

1. Under Style, set the title, palette and size (square sizes suit radar charts).
2. Download PNG, SVG or JPG, or copy the image.

Reading a radar chart

Each spoke is one measure; the further out a point, the higher the score. Joining a series' points makes a shape:

• A large, round shape — strong across the board.
• Spikes — particular strengths.
• Dents — weaknesses.
• Overlapping shapes — where two subjects are similar; gaps show where they differ.

Good uses

• Skills profiles — team members or candidates across competencies.
• Product comparisons — price, quality, speed, support, features.
• Performance reviews — several KPIs at once.
• Sports — players' attributes.
• Self-assessment — a "wheel of life" or a course's learning goals.

Getting it right

• Same scale for every measure. Radar charts only make sense when all spokes use one scale (all out of 10, all percentages). Convert different units first.
• Higher should mean better on every spoke. If one measure is "lower is better" (like price or errors), flip it — score it so that a high value is good.
• Five to eight spokes. Fewer looks like a triangle; more becomes hard to read.
• Two or three series. More overlapping shapes turn into a tangle; use a bar chart with grouped bars instead.
• Show values when precision matters: shape areas exaggerate differences, because area grows with the square of the scores.

Spoke order matters

The shape depends on which measures sit next to each other. Group related measures (all technical skills together, all people skills together) so the shape tells a story — "strong technically, weaker on people skills".

Values above the maximum

If you set the maximum yourself and a value is higher, it's drawn at the rim and the tool tells you, so you can raise the maximum.

A worked example

Comparing two job candidates on six competencies scored out of 10: set Scale maximum to Set it myself and 10, choose Polygon (web) with 5 rings, and tick Show values. One candidate's shape bulges towards the technical spokes, the other's towards communication and leadership — a quick visual summary for the hiring panel, with the exact scores still visible.

Frequently asked questions

How many series can I compare?

As many columns as you paste — but two or three read best.

Can values be negative?

Radar charts start at zero at the centre; negative values are drawn at the centre.

Why does my chart look like a triangle?

You have three measures. Add more rows for a fuller shape.
